Negative stiffness self-resetting viscous damper
The invention relates to a negative-rigidity self-resetting viscous damper which comprises a first end and a second end which are connected with different structural parts respectively. The self-resetting viscous mechanism is fixedly connected with the first end and comprises an outer cylinder, a first connector arranged in the outer cylinder, a main cylinder, an annular spring, a second connector, a first piston rod, a second piston rod and the like; the spiral spring fixing seat is mounted on the outer cylinder; and the spiral spring assembly is arranged on the spiral spring fixing seat. According to the damper, in the earthquake process, the piston reciprocates in the damping medium to dissipate earthquake kinetic energy, the annular spring dissipates energy through self friction, the cylindrical spiral spring provides negative stiffness effect, and the dynamic response of the structure is reduced.
本发明涉及一种负刚度自复位粘滞阻尼器，包括：分别连接不同结构件的第一端头和第二端头；与所述第一端头固定连接的自复位粘滞机构，其包括外筒，设置在所述外筒内的第一连接头、主筒、环形弹簧、第二连接头、第一活塞杆和第二活塞杆等；安装在所述外筒上的螺旋弹簧固定座；以及设置在所述螺旋弹簧固定座上的螺旋弹簧组件。本发明提供的阻尼器在地震过程中，活塞在阻尼介质中往复运动耗散地震动能，环形弹簧通过自身摩擦耗能，圆柱螺旋弹簧提供负刚度效用，减小结构的动力响应。
